结果表明，无论是否满足定标律，大气湍流会引起多色部分空间相干光的光谱移动和光束扩展；多色部分空间相干光光束扩展比多色完全空间相干光受湍流的影响小。

It is shown that the atmospheric turbulence gives rise to spectral shift and to beam spreading of spatially partially coherent polychromatic light whether the scaling law is satisfied or not.

利用非相干光相关操作处理和空间移位编码方法，实现了基于相似性度量的灰阶图像匹配处理。

Using an incoherent optical correlator and a shift encoding method, the processing of gray sclae image matching based on similitude measurement was realized.
